💅 xe_guc_pc_init(9) — the Kernel API Manual moment

okay so bestie, welcome to xe_guc_pc_init(9) from the Kernel API Manual ✨ this is the lil glow-up page for the GuC's Power Conservation component, and honestly it's giving "small function, big job" energy.

🌸 NAME 🌸

xe_guc_pc_init — literally just Initialize GuC's Power Conservation component 🫶 that's the whole vibe. no notes.

✨ SYNOPSIS ✨

int xe_guc_pc_init (struct xe_guc_pc *pc );

it returns an int, it takes one pointer, and yes the spacing is exactly like that — copy it character for character, no cap 😌

🎀 ARGUMENTS 🎀

• pc — your Xe_GuC_PC instance 💖 the main character of this whole operation. that's it, that's the only argument, she's lowkey simple like that.

🦋 SEE ALSO 🦋

okay this is the part where the page just keeps going, and we respect her for it 👑

like look at that list — a whole friend group of frequency getters and setters 💀 every single one of them made it onto this page, and they all said "iykyk".

and that's the whole page, bestie 🍓 nothing scary, no warnings, no undefined behaviour lurking in the shadows — just a little init function and her extremely long list of besties.

fr fr the only rule here: pass her a real struct xe_guc_pc * and let her cook 🔥

mwah 💜 this page came to us from the source/version line ./drivers/gpu/drm/xe, dated October 2026, and the title up top is xe_guc_pc_init(9) — iconic, timeless, periodt 🌈👑
